KYB Suspension Shock Absorber P/N:553385
Bring back your truck's original ride control and handling with the KYB shock absorber 344045, a nitrogen gas-charged, twin-tube Excel-G rear shock built on the same KYB OE assembly lines that supply new-vehicle manufacturers. This KYB Excel-G gas shock absorber is calibrated to restore your vehicle's designed performance rather than change it — earning it KYB's OEA (Original Equipment for the Aftermarket) classification. It installs as a direct-fit replacement in the rear position for the 1980-1982 Chevrolet LUV, 1987-1993 Dodge Ram 50, 1983-1994 Mitsubishi Mighty Max, 1987-1995 Nissan Pathfinder, 1979-1983 Toyota Pickup and more — see the Buyer's Guide tab for the full list and engine details.
Shocks work as a pair — replacing both rear units together supports even, balanced ride control.

This part cross-references / interchanges with the following part numbers:
Is this KYB Excel-G shock absorber for the front or rear?
This 344045 is a rear shock absorber. It is sold individually; for even, balanced ride control we recommend replacing both rear shocks together as a matched pair.
What is the KYB gas shock absorber Excel-G design?
It is a nitrogen gas-charged, twin-tube design made on KYB's OE assembly lines using OE-quality components, calibrated to restore your vehicle's original designed performance.
Does the KYB shock absorber fit my Nissan Pathfinder?
Yes — it is listed for the 1987-1995 Nissan Pathfinder in the rear position. Always confirm your exact year and model against the Buyer's Guide tab before ordering.
What does the triple lip fluid seal do?
The triple lip fluid seal reduces the chance of oil and gas leaking out of the shock, helping the unit maintain consistent damping performance.
What are signs my shock absorbers may need replacing?
Common signs include excessive bouncing after bumps, nose-diving under braking, uneven tire wear, or visible fluid leakage. Have the suspension inspected to confirm the cause.
